MACHINE FOR ROLLING AXLES.

' SPECIFICATION forming part of Letters Patent No. 463,541, datedNovember 17', 1891.

Application filed January 17, 1891. Serial No. 378,165. (No mbdel.)

To ail whom it may concern.-

' Be it known that I, JAMES S. PATTEN, of Baltimore city, in the Stateof Harylanchhave invented a new and useful Improvement in Machines forRolling Axles, of which the following is a specification.

My invention is an improved machine for rolling vehicle-axles, and hasfor its objects, among others, to provide a simple novel constructionwhereby to roll both the spindle or arm and the body portion of theaxle-section, such as shown in Figure 6; to provide a simple,easily-operated, and effective feed for the axles, and to providecertain improvements in the general construction of the machine; towhich ends the invention consists in certain novel constructions andcombin ations of parts, as will be hereinafter described, and pointedout in the claims.

In the drawings, Fig. 1 is a top plan view of my machine. Fig. 2 is aside elevation showing therolls for forming the spindles of the axles.Fig. 8 is an elevation of the side opposite that shown in Fig. 2. Fig.at is alongitudinal section of the machine. Fig. 5 is a cross-section ofthe machine. Fig. 6 is a detail view of the completed article rolled inmy machine. Fig. 7 is a detail section on about line 7 7 of Fig. 2, andFig. 8 illustrates how the feeder-plate engagesthe shoulder of the axle.

In the construction shown the frame is formed of a base A, end uprightsB B and O O, a side plate or frame D, extended between the uprights C(J, and the side plates or frames E and F, extended between the uprightsB B, the frames D and E being arranged sufficiently apart to admit themain or long rolls between them and the frames E F being arrangedsufficiently apart to receive between them the short 'rolls for formingthe spindles upon the axle-bars, as presently described. A table G, Fig.4, is arranged in about a horizontal line with the contact-surfaces ofthe rolls of the several pairs, and is provided with longitudinal guidegrooves or channels g to direct the axles in the passage thereof throughthe machine. The rolls are arranged in pairs and in line, so that theaxle may pass directly from one pair of rolls to the next.

In the construction shown I employ three pairs of rolls, each having themain rolls H for forming the body or axle proper, and the rolls I forforming the spindles of the axles. The rolls of each pair are gearedtogether by means of gears J J, and the lower roll of each pair isgeared with that of the next pair or pairs by intermediate gears K, sothat the several rolls are properly driven as desired. A suitableband-pulley L is provided on the shafts of one of the rolls. I providethe gears .I J and K at the ends of the main rolls, as shown in Fig. 5.In the end rolls Iare formed the cavities or grooves 1', extendedlongitudinally in the direction of the axis of the rolls and leading outof the ends of such rolls. The grooves of the upper and lower rolls Iare shaped to form the spindle and collar of the axle, and in operationthe billetis placed at one end sidewise to or parallel the rolls I andthen passed sidewise between the said rolls.

In practice the several pairs of rolls-I are preferred, as the firstpair will give the general form to the spindle, the next pair bring suchspindle into better shape, and the third pair finish the formation ofthe spindle, as will be readily understood.

It should be understood that my machine is intended for use in rollingcarriage and wagon axles of that class which are made in two sectionswelded or otherwise united at their inner ends, the present machinebeing designe d forrollingsuch sections from suitable billets or blanks.Now in operation the rolls I operate to roll the spindle and collarportion, (see Fig. 6,) while themain rolls H serve to roll the bodyportion, also shown in said Fig. 6. It will be seen, therefore, that thebillet suitably held is placed at one end sidewise to the first pair ofrolls I passed therethrough, and so on through the several pairs of saidrolls I. This completes the shoulder and spindle portions, leaving thebody part un-' rolled. Now the article is fed to the main rolls H, thegrooves h thereof being adapted to receive the rolled spindle andshoulder, and the article being fed through the rolls H the body partwill be properly rolled into the form shown in Fig. 6. The manner inwhich the feeder engages the axle is clearly shown in Fig. 8.

For the purpose of affording easy access to the rolls I it is preferredto provide a slotor opening f, Fig. 2, in the side plate or frame F. Itwill be noticed that a table or platform G, Fig. 2, is provided betweenthe framesE F at the bottom of the slot f. The main rolls ll areprovided with circumferential grooves 71,

having portions to receive the finished spindle parts and portions it toform the body of the axles. The portions h, Fig. 4c, in the successiverolls approach the completed shape of :o the body of the axles until thefinal rolls finish the axles, as will be readily seen.

In practice I provide the rolls II with several sets of grooves h,adapted to roll the different varieties of axles, so that the machine I5 may be used for rolling any of the ordinary forms of axles. Thegrooves h are arranged in line with the grooves or ways g, so that thesaid grooves g serve to direct the billets or bars to the grooves h andout of the machine.

In feeding the billets or bars from the rolls H to the next pair andfrom the last pair of such rolls out of the machine I employ a feeder M,Fig. 4, consisting of a frame N and feedingplates 0, preferably ofspring metal, depend- 2 5 ing therefrom and having their lower free endsforked at 0 and movable forward within and back above the grooves orchannels g. I provide the frame N with as many sets of feeding-plates Oas there are pairs of rolls H 0 to feed the axles to such rolls and alsoone extra set to feed the axles from the last pair of rolls out of themachine. Each set of plates has as many plates 0 as there are grooves 7bin the rolls H, as will be readily 5 understood from the drawings. Theframe N is given a forward movement in one plane and a backward movementin a higher plane, being lifted at the beginning ,of its backward strokeand lowered at the end of such stroke. This is effected by providingguide grooves or ways P for the lateral pins 19 of the frame, such waysP being formed, as shown, with upper and lower longitudinal portions P Pa rear connecting portion 12,

5 and a front connecting portion 19 This portion 19 is controlled byapivoted drop-leaf Q, which lifts as the pin pengages its under side atthe end portion of the forward movement of the main frame, and thenforms an so inclined guide, up which the pins 13 travel to the upperportion P of the guideway P at the beginning of the backward stroke ofthe frame. The operation of this construction as the feed-frame isreciprocated will be read- 5 ily understood. To effect the reciprocationof this frame N, I connect it with one of the rolls, preferably in themanner shown, in which slots R R are formed in the outer frames D and F,and the feed-frame has a rod or bar projecting through the said slotsand connected with one end of pitmen S, which are connected at theirother ends to crank-arms T on one of the rolls. By preference the rollwith which the pitman con nects is arranged with reference to the pointof connection of the pitman with the frame, substantially as shown, sothat the pitman will operate with a pushing action in forcing the studsof the frame to ride up the pivoted drop leaves or gates Q of theguideways I. The side frames D F are recessed at t for the crank'arm T,so that the pitman can be arranged close to the said side frames, asshown.

In operation the billets or bars are applied to the side rolls in themanner described and the spindles are rolled thereon. The billets arethen placed in the grooves g at the front of the machine and are fed bythe feeder to the first pair of rolls, the feeder being adapted to graspthe axle just back of the collar and being so timed with reference tothe movement of the rolls that it' will feed the spindle properly intothe part of the roll formed to receive it. After being drawn through thefirst pair of rolls the next feeding-plate grasps the axle and feeds itto the next pair of rolls, and so on. Manifestly the number of rolls maybe increased at will, and it will also be understood that the form ofthe cavities in the rolls may be varied to roll any desired form ofspindle or axle-body. In rolling it is usual to apply water in suitablemanner to the iron for the purpose of removing scale.

Having thus described my invention, what I claim as new is 1. Animproved machine, substantially as described, comprising a framing, apair of main rolls having around their circumference grooves or cavitiesadaptedto form the body of the axle, and a pair of end rolls providedwith grooves or cavities adapted to form the spindle of the axle, suchgrooves being formed to open out at the end of the end rolls and beingextended in a line parallel to the axis of said end rolls, allsubstantially as and for the purposes set forth.
